"Syrian air defenses spread out to target US as well as Israeli overflights"
military officials are cited . . . as
estimating on Thursday that the combined Russian, Syrian, Iranian and
Hizballah army massing on the western bank of the Euphrates in the Deir

US-backed SDF (Syria Democratic Forces), which is composed mainly of
Kurdish YPG militiamen. Their particular targets are the CONICO gas
facility and the al-Omar oil fields."
